96 KByte Flash Module (S12FTMRG96K1V1)
1 _{Global address [2:0] must be 000}
Upon clearing CCIF to launch the Program P-Flash command, the Memory Controller will program the
data words to the supplied global address and will then proceed to verify the data words read back as
expected. The CCIF flag will set after the Program P-Flash operation has completed.

Error Condition
Set if CCOBIX[2:0] != 101 at command launch
ACCERR
Set if command not available in current mode (see Table 28-27)
Set if an invalid global address [17:0] is supplied see Table 28-3)¹
FSTAT
FPVIOL
Set if a misaligned phrase address is supplied (global address [2:0] != 000)
Set if the global address [17:0] points to a protected area

Set if any non-correctable errors have been encountered during the verify
operation

28.4.6.6 Program Once Command
The Program Once command restricts programming to a reserved 64 byte field (8 phrases) in the
nonvolatile information register located in P-Flash. The Program Once reserved field can be read using the
Read Once command as described in Section 28.4.6.4. The Program Once command must only be issued
once since the nonvolatile information register in P-Flash cannot be erased. The Program Once command
must not be executed from the Flash block containing the Program Once reserved field to avoid code
runaway.

Upon clearing CCIF to launch the Program Once command, the Memory Controller first verifies that the
selected phrase is erased. If erased, then the selected phrase will be programmed and then verified with
read back. The CCIF flag will remain clear, setting only after the Program Once operation has completed.
